BIELT FASTENER.

SPECIFICATION forming part of Letters Patent No. 399,962, dated March19, 1889.

Application filed November 12, 1888- $eria1 No. 290,529. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM G. AVERY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Improvement in Belt-Fasteners, of which thefollowing is a specification.

My invention relates to improvements in belt-fasteners, and my design isto produce a detachable belt-fastener in two portions for thecorresponding ends of the belt without the aid of intervening mechanism,and at the same time to produce a simple form of construction which willdistribute the strain over the greater portion of the surface offastener and relieve the strain on the rivets, and which can be stampedfrom sheet metal at low initial cost. These objects are attained in theconstruction shown in the accompanying drawings, and more specificallypointed out in the claim.

In the drawings, Figure l is a section of belt in which the joint isheldby means of two of my improved fasteners. Fig. 2 a 1011- gitudinalsection of the same. Fig. 3 is a perspective view of the detached partof the fast ener, and Fig. 4 is a modification of the same. Figs. 5 and5 show a pin inserted in the T- head to strengthen it.

A and A in the drawings represent the different portions of thefastener, which are formed of thin plates of steel'struck out by a dieand afterward bent to the required form.

B and B are rivets passing through the holes C and C in the plates,which serve to bind the faces of the plates together upon the belt. AT-headed slot, 0, is cut in the head inclosing shoulders cl, the T-headcannot possibly get out of the slot of its own accord. The corners c arerounded by pieces of metal left for this purpose, to avoid the sharpedges that might otherwise be left. The rivets B and B are not intendedto take the strain of the belt, but are relieved from it by the points fand f, struck from the surface of the clamps, which project into thebelt and serve to distribute the strain equally over the belt instead ofmerely in the line of the rivets. The rivets serve to hold these tightlyagainst the belt and prevent slipping. A modified form is seen in Fig.t, where the points f are struck across the end of the clamp and turnedtoward each other, effectually holding the leather.

My clamp, being formed of sheet-steel, may be quickly and economicallymade, and is new in its construction and useful for the purposes forwhich it is intendedto distribute the strain equally over the belt. 6

It will be observed that my clamp becomes embedded in the belt, and bymeans of the points on the surface will hold the belt independently ofrivets.

In cases where it is desirable to use thin metal for the fastener, or incase of wear, a steel pin may be inserted to re-enforce the T- head, asshown in Figs. 5 and 5.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

The detachable sheet-metal belt-fastener, consisting of the piece A,having a T'-slot, and the opposing piece A, having a T head formedintegral therewith, both pieces being provided with inwardly-projectingteeth and rivet-holes, substantially as shown.

WILLIAM G. AVERY.
